SUMMARY

INTRODUCTION

In 2006 Arlington County passed a bond referendum which included

the funding of design for improvements or replacement of Wakefield

High School. Bowie Gridley Architects (BGA) was engaged by

Arlington Public Schools to analyze the requirements and generate a

building design to serve the needs of the Wakefield and greater

Arlington communities well into the future. This Schematic Design

Report documents the second primary phase of that process.

The previous Feasibility Study Report dated August 9, 2007,

documented the feasibility process and studies. This included

documentation of the existing programs, site and facilities of the

current Wakefield High School, a summary of the Educational

Specification for the new building, review of the Planning Principals

and Design Goals that guided the feasibility design studies, and

documentation of multiple design options.

The Feasibility Study was developed working closely with APS staffand the Building Level Planning Committee (BLPC) appointed for theproject. Upon further review by both the Arlington County Board andthe School Board, as well as the new County Board appointed PublicFacilities Review Committee (PFRC), a set of key ConceptCharacteristics and Schematic Initiatives were approved as the basisfor commencing the Schematic Design. This Schematic Design Reportdocuments the further development of the approved ConceptCharacteristics and depicts the design for a new Wakefield High School.

SCHOOL OVERVIEW

Wakefield High School is located at 4901 South Chesterfield Road inthe southern part of Arlington County, Virginia. One of three publiccomprehensive high schools in the county, it has served a studentbody of roughly 1,400 in recent years. The school has earned a national

reputation as an institution that has fostered high academic achievementfor all its students regardless of social, economic and developmentaldifferences. The school has also achieved success outside of theclassroom with its athletic, music and theatrical programs creating anexciting and comprehensive educational environment often referred toas the “Wakefield Way”. In addition to serving the students, Wakefieldprovides a significant amenity to the surrounding community, with bothits fields and program areas, such as the Aquatics Center, Auditorium,Library and others, making it a key community institution.

Wakefield first opened in the mid 1950’s as the Wakefield Junior-Senior High School, and has since undergone a number of additionsand renovations, including the ‘English Wing’ and the Library expansion.Despite Wakefield’s many successes, the current building andinfrastructure do not meet current programmatic, safety and comfortrequirements to foster a first class education for students. Thiscondition necessitates its replacement.

FEASIBILITY CONCLUSIONS: CONCEPTCHARACTERISTICS AND SCHEMATIC INITIATIVES

After conclusion of the Feasibility Phase and subsequent considerationby the BLPC, PFRC, County and School Boards, the Arlington SchoolBoard approved the following Concept Characteristics. These servedas the basis for the Schematic Design.

CONCEPT CHARACTERISTICS

• Preserve existing treed slopes, and existing stadium and tenniscourtsThese existing, valuable, and difficult to replace amenities should bepreserved.

• New 3 story school (with partial lower level) at corner ofDinwiddie and George MasonRenovation and reuse of the existing building was determined to betoo costly and significantly extended the construction period causingexcessive interference with the educational mission of the school.This site has room to develop a new school without significant impact

on the use of the existing school. The design should place the buildingat the most public, prominent corner and maximize usable open space.

• Pedestrian entrance along George Mason, primary vehicularaccess off Dinwiddie, service access off George MasonThese access arrangements work with the natural paths taken to thesite, maximizing the opportunities provided by the existing transportationnetwork and site topography.

• Outdoor arrival spaces introducing the entrances and providingstudent gathering space off the streetIt is vital to provide safe and welcoming outdoor spaces at all entrancessufficient to accommodate the large numbers of students convergingat key times of day.

• Main entrance welcoming the majority of users and supervisedby AdministrationThe building must be both welcoming and provide clear and supervisedentrances.

• Major program elements and relationships, including a centralhub or “Heart”The program relationships illustrated in the Concept Diagram, includinga central hall, should be maintained and expanded.

• Looped interior circulation around an internal court.Due to the number of students circulating through the buildingsimultaneously, it is important not to create dead ends and to provideredundancy in a looped circulation system.

SCHEMATIC INITIATIVES

In addition to the above approved Concept Characteristics, the SchoolBoard also incorporated these County and PFRC Schematic Initiativesto guide the further evolution of the design in Schematics:

• Ensure civic presence and charisma and address both streetsThe building will be constructed on a prominent corner at the boundarybetween Arlington and Fairfax counties, and the building shouldembody civic presence and charisma representative of ArlingtonCounty.

• Less prominent Arrival Space along DinwiddieThe Feasibility Phase diagram shows vehicular circulation spacesand outdoor arrival spaces between the building and Dinwiddie Street.The reduction of these elements will assist the building in achievingits civic presence.

• Lessen impact of busesAs a community with a multi-modal transportation focus, it is desirablenot to draw significant attention to the vehicular transportation modescoming to the site.

SUMMARY

SCHEMATIC DESIGN DESCRIPTION

Bowie Gridley Architects, working closely with the BLPC and APSsaff, as well as the newly formed PFRC, developed a series of designiterations that met the approved Concept Characteristics andSchematic Initiatives. The resulting design meets the broad needs ofthe public and educational mission of the schools, as well as thespecific programmatic needs of the Wakefield faculty and staff,embodying the “Wakefield Way.”

The Schematic Design places the new building in the southwest cornerof the site, at the intersection of George Mason Drive and DinwiddieStreet, on the site of the existing baseball and softball fields. Thislocation will allow the new building to be built while continuously keepingthe existing school in operation. It also provides for civic presence atthe key intersection and removes the building from the single-family

residential areas of the neighborhood. A consolidated parking area,roughly centered on the Dinwiddie Street frontage, will serve both schooland community users of the building, as well as the outdoor recreationalamenities.

The building is a fan shaped form spanning from an alignment withDinwiddie Street on the south to an alignment with the rotated stadiumaxis to the northeast. There are three main public corridors that thebuilding is organized around: a linear corridor running from GeorgeMason Drive to the central parking lot and two curving corridors runningfrom Dinwiddie Street to the stadium. The mass is divided into a 3story ‘A’ shaped Academic Wing fronting on Dinwiddie and GeorgeMason, and a 2 story lower level Athletic Wing fronting on the lowerportion of the Stadium bowl. The one story connections betweenthese wings form a series of courtyards that provide abundant naturallight into the interior of the building and gathering spaces for students.The primary entrance is focused on the central parking lot and busloop, and a major corridor axis extends toward George Mason, withthe hall terminating on an entrance aligned with Frederick Street.

The school is zoned vertically, with the more public anchor uses suchas the Auditorium, the Aquatics Center, the Gymnasium, the Library,the main administrative spaces, and the central Town Square / Heartlocated on the ground floor. The upper two floors of the AcademicWing contain classrooms, and other student focused spaces moresegregated from the public. The lower floor of the Athletic Wing containsthe main gym, lockers, a fitness room, and other athletic spaces.

BUDGET AND SCHEDULE

The area of the Schematic Design is a total of 380,970 gross squarefeet (gsf) on four floors. The largest level, the ground floor, has afootprint of 171,250 gsf, which reduces to 49,030 gsf on the lowerathletic level, and to roughly 80,940 gsf each on the upper two floorsof the ‘A’ shaped Academic Wing. The estimated construction cost ofthe Schematic Design is $87 million in 2009 dollars, for a total estimated2009 project cost of $105 million. It is anticipated that the new buildingwill be bid in 2013 and be occupied in the autumn of 2016. Estimatedproject costs escalated through 2013 range from $119 million to $167million depending on market assumptions. This cost estimate andthe size and quality of the building are consistent with the equity andbudgetary goals set forward by the School Board in the FeasibilityPhase. See section 07 for additional detail.

ACCESSIBLITY

The Schematic Design complies with universal design requirements.All three primary entrances will have on grade access and approachesby accessible routes. The lower gym and athletics level and thestadium and tennis courts, will be accessed off a sloped site walk ata 5% grade. Within the building there will be 3 elevators providingvertical access for the Athletics Wing, the Academic Wing, and withinthe Aquatics Center serving the spectator mezzanine. Accessibleparking is provided at the main lot and directly adjacent to the stadiumgrandstands and tennis courts. A pathway across the site from GeorgeMason Drive to Chesterfield Road will be fully accessible as well.

PLANNING PRINCIPLES (Feasibility Process)To initiate the design studies, general Planning Principles were discussed and illustrated with a varietyof diagrams and images. A facilitated discussion of these concepts led to a ranked list of principles.Expanding on these, the committee created a list of Design Goals for both the site and the building.These were utilized in the evaluation and ranking of the Design Schemes.

Design Goals (Feasibility Process)Through a series of BLPC meetings, the following goals were established:

Site

Create a civic presence and engage communitythrough appropriate siting of the building.

The School, as a major public structure and focal point for commu-nity activities, should be welcoming, accessible, and prominent. Itshould have a civic presence commensurate with its status as a majorpublic institution, while being careful not to overwhelm smaller ad-joining properties.

Develop pedestrian routes through and around thesite to improve walking access.Recognizing that roughly 1/3 of all students arrive by foot, and thedesire to encourage walking for all visitors to the site, convenientand attractive walkways around, across, and to all major amenitieson the site should be provided. Conflicts between pedestrians andvehicles should be minimized.

Create attractive and useful outdoor spaces forteaching and informal gathering.Students, visitors, and community users of the school and fields needcomfortable places to wait, gather informally, and socialize. Outdoorspaces for class instruction are a resource for a flexible and usefulteaching environment. The landscape surrounding the school shouldcompliment the full variety of these exercises.

Develop clear and separated vehicular circulationroutes.

School bus, faculty, student, staff and visitor parking, ‘kiss and ride’drop off, and service traffic should have clear substantially separateroutes to avoid conflicts and make arrival by vehicle welcoming.

Natural areas, such as mature individual trees and wooded areas,should be conserved to the greatest extent possible as environmen-tal and aesthetic community resources. Also, high value athletic im-provements such as artificial turf, irrigated fields, bleachers, lightingand other infrastructure should be preserved.

Conserve natural areas and retain existing athleticamenities to the greatest extent possible.

PLANNING PRINCIPLES (Feasibility Process)

Create a main entrance for the majority of userswhich is clear, inviting and secure.

The entrance used by the majority of users of the school should alsobe the symbolic main entrance or “front door.” This “front door” shouldhave a civic presence appropriate to the school’s status in the com-munity, and architectural cues which ensure easy navigation and asense of openness for visitors. The combining of the functional andsymbolic main entrances allows enhanced supervision and security.

In addition to the “front door”, secondary entrances should be pro-vided for uses, such as athletics and aquatics, which also functionwhen the main school facility is closed. In addition, pedestrians ap-proaching the building from George Mason Dr. need a clear and wel-coming entrance, which connects to the main corridor. All entrancesshould be clear for their respective uses.

Create secondary entrances to provide access for school& community use.

Establish a “heart” as a symbolic centercomplimented with smaller informal gathering areas.

Distribute administration throughout the buildingand maximize passive security.

In a large and diverse environment like a high school for 1600 stu-dents, it is important to provide a sense of place, a symbolic “heart”that gives the school an identity to its community. Small open gath-ering spaces should be included throughout the building to compli-ment “the heart.”

Administrative functions provide centers of adult activity within theschool, providing passive supervision of interior spaces. Administra-tive presence is particularly important at all entrances. Security sys-tems should support this strategy and provide a secure school.

Express sustainability principals and design toLEED silver level.

Group assembly spaces to create a synergy ofschool and community uses near convenientaccessible entrances.Utilize significant academic and public spaces, corridors and stairsto create vibrant interior environments within the school. Create athoughtful mix of program spaces that encourages user interaction.

Environmental sustainability is a key value of Arlington Public Schoolsand the broader Arlington community. The school should both incor-porate appropriate sustainable design approaches and resource con-serving technologies, and celebrate and make visible those valuesand techniques.

SCHEMATIC DESIGN

SCHEMATIC SITE PLAN

The site is bounded by roads on 3 sides, and is roughly square in

shape with George Mason Drive forming the west edge, Dinwiddie

Street forming the south edge, and Chesterfield Road forming the east

edge, while the north property line adjoins residential back yards. The

topography of the site is divided into several main areas. The largest

is the roughly flat zone forming a reversed ‘L’ shape, following the full

lengths of Dinwiddie and Chesterfield and on level with those roads.

The center of the site is a valley, in which the existing stadium and

tennis courts are located about 1 story below the streets. In the

northwest quadrant of the site is an existing stand of mature hardwoods,

covering a significant slope that follows George Mason as it slopes

downhill away from the site to the north.

The new building will be sited on the prominent southwest corner of

the site, on the reversed ‘L’ shaped main level area, where the baseball

field is opposite the existing building. This will allow the new building

to be completed while the existing school is in full use without

interruption of the academic schedule. It also moves the bulk of the

school from the smaller scaled area of the site, and places it adjacent

to the busiest road, and at the civic corner where Dinwiddie and George

Mason meet the Arlington and Fairfax border. This location also provides

opportunities to take advantage of views into the adjoining wooded

area to be preserved, and takes advantage of the natural screening

along George Mason to conceal the service area.

The new parking area is located midway along Dinwiddie Street and

central to the site, allowing it to serve the athletic fields, the school,

and after-hours community uses. This central location improves on

the distributed existing parking and should encourage students and

other users to park on site rather than on neighborhood streets.

Surrounding the parking lot will be the bus loop, which will provide

students with direct access to the main school entrance, and during

off hours provide additional parallel parking for large events.

The existing stadium, tennis courts and multi-purpose/ soccer field

on the north half of the site will remain, with improved access and

additional parking provided adjacent to the multi-purpose field. Alternate

ticketing, concessions, and toilet facilities are included as an option

within the design which will improve the usability of these areas as

well. Upon demolition of the existing school, the baseball and softball

fields will be rebuilt on the southeast corner of the site, and will include

improved orientations, size, and amenities, and access from the central

parking lot. New plantings will help to screen the brightness of the

lighted fields from nearby houses.

The primary pedestrian flows to the site come from the northwest

along George Mason, the northeast from Barcroft along Chesterfield,

and East along Dinwiddie. The walkers coming to the building along

George Mason or from Frederick will be received by a new landscape

plaza and pedestrian entrance to the building. They can also move

laterally across the site on a pathway that skirts between the Athletic

Wing and the existing wooded area, past the stadium, tennis courts

and new ball fields, and ends at Chesterfield. Walkers coming to the

building from the northeast and east can use the extensive new

walkways to approach the buildings through the Rain Garden/Entrance

Courtyard.

The site will have a more urban frontage along Dinwiddie adjacent to

the school and parking lot, with broad walks and double rows of street

trees, and a more park like streetscape to the east bordering the

fields. A naturalistic area will be developed to the north with the

Commons formed between the building and the existing wooded

slopes. Both the Rain Garden, between the Athletics Wing and the

Academic Wing, and the Bioretention areas in the parking lot, will

serve as living filters for stormwater run off, as well as attractive

symbols of Arlington’s commitment to sustainability.

SCHEMATIC DESIGN

SCHEMATIC PLANS

The building form consists of several wings or bars arrayed in a fan

shape, resolving the dual requirements for the building to be parallel

to form a street edge on Dinwiddie Street and to front on the stadium

and athletic areas to the east.

The first two bars of the fan shape form an ‘A’ shaped, 3 story

Academic wing massed along Dinwiddie Street, and provide a

pedestrian oriented front door to the school. The point of the ‘A’

holds the Auditorium and music program spaces, placing them in a

location convenient to the public, and giving them a distinct identity

within the school. The two legs of the ‘A’ extending toward George

Mason house the general classrooms serving the majority of the

academic programs. The specialty lab spaces of the science

department are expressed as a special element on two floors between

the bars. The extended legs of the ‘A’ also serve to shelter the service

area along George Mason Drive along with the natural grade and

existing trees.

The third bar consists of the Athletic Wing housing the aquatics center

and main and auxiliary gyms. The main competition gym floor is

dropped a story below the entrance level to provide separation of the

players from spectators entering from the tops of the bleachers. The

core of the athletics program is on level with the stadium and tennis

courts and will provide restroom facilities to users of the exterior

amenities. The aquatic portion of the Athletics Wing is at the parking

lot end of the bar, giving it visual prominence and allowing it to have

independent access.

Between the Academic and Athletic Wings are several one story spaces

including the Library, main administrative suite, and a series of exterior

courtyard spaces which serve several programmatic functions and

bring light and views to the interior of the building. All this is bound

together by a circulation network of a main axial corridor, and two

radial corridors. At the center of the building is the Town Hall. This 2

story open space serves a programmatic function as a part of the

Cafeteria and acts as the main civic space of the school. It fronts

directly onto its own central courtyard which serves both as outdoor

dining and as an extension of the Town Hall. It provides well supervised

outdoor space critically lacking in the existing facility.

The other courtyard, flanked by the main entrance and athletics entrance

canopies, and fronting upon the main parking and bus loop, will be

developed as a rain garden. This will provide an attractive landscape

feature that performs important storm water management functions

and represents Wakefield’s strong commitment to sustainability.

PROGRAM DISTRIBUTION

The primary program elements which will be used by the community:

the Pools, the Gyms, the Auditorium and Studio Theater, the Library,

the Large Group Meeting Room, and the Town Hall are all located on

the ground floor, and are closely accessible from the primary parking

lot and main entrances. The Aquatics Facility has its own separate

entrance for the public through a shared vestibule with the school,

allowing the public to access the pool independently. The ground

floor will incorporate divider gates allowing zoning of the school for

public use, while still securing upstairs classrooms and other non-

public spaces.

SCHEMATIC DESIGN

ELEVATIONS & MASSING

As the design team of Bowie Gridley Architects and the BLPC and

APS Staff worked on the design, several ideas were essential to

developing the elevations and materiality of the school.

EXPRESSION OF THE WAKEFIELD WAY

Open and Welcoming: Hand in hand with its diversity, Wakefield

takes pride in being a facility open to the community, students,

their families, and the greater Arlington public. This can be expressed

architecturally as a building with a sense of openness, where the

internal activities of the school feel visible and accessible to those

outside. The welcoming nature of the Wakefield Way can be

embodied in a facility whose entrances are attractive and easily

found, and have the sense of seamless transition from the exterior

to the interior.

Informality: Wakefield seeks to extend that congeniality by an

informality that is intended to be counter to the sense of

institutionalism, rigidity, or intimidation in many public schools.

Internally, this is expressed by such simple moves as the Principal’s

office having a door directly to the hall that can be left open, or by

providing comfortable spaces and furnishings to allow spontaneous

gathering and interaction. On the exterior, the school building can

express this informality by a non rigid, asymmetrical form, and by

inviting natural landscapes to extend into the building through

courtyards.

Forward Looking and Technology Focused: Wakefield is an educational

community focused on equipping students with general and specific

skills important to their lives in the 21st century. It has an emphasis on

science and computer instruction. While fitting in with its neighborhood

in its massing and detail, it is desirable to celebrate a contemporary

architectural style.

Appropriate Lighting and Views: The windows of the school are its

eyes, both looking outward and bringing light in. Students need both

visual relief from the interior environment, and abundant natural light to

avoid strain and assist in concentration. The envelope of the building

should accommodate thoughtfully placed glazing and provide good

daylighting and attractive views.

Form Celebrates Function: The design team has sought to create a

school whose rooms and spatial relationships best serve the complex

needs of the Wakefield community, while embodying the fun, informality,

welcome and openness of the Wakefield Way. The resulting building

should neither hide this practicality, nor formulaically follow it. The

architecture should be engaging and invite an understanding of the

building’s uses and functions.

MATERIALS

The design incorporates several materials as its basic palette withwhich to enliven and express the ideas of the building.

Masonry: A durable material that expresses the longevity andpermanence appropriate to a major civic institution, masonry is thedominant material which forms the building. Two colors of brick willbe used to form the Cassroom and Athletics bars creating the basis ofthe geometry. The weight of the masonry is expressed, while celebratingthat it is a modern, steel framed building where the brick is supportedas a veneer.

Metal: Metal panels form a separate major system expressing specialspaces, including athletics, performing arts, and sciences. Thematerial embodies the technological focus of the school and is a highlydurable and proven cladding system.

Glass: Aluminum framed high performance glazing, in both window,storefront and curtainwall systems, form the final major material. Theglazing opens the building and provides another material with which tocelebrate important spaces.Detail at Bus Loop

TYPICAL CLASSROOMS

TYPICAL CLASSROOMS

The typical classrooms and their grouping were extensively discussed

during the Feasibility phase with the staff and the BLPC. It was

determined that the educational offerings and groupings were too fluid

to be concretized into any single architectural expression, and so a

more general classroom layout that allowed flexibility was selected.

All the classrooms serving the general academic needs are grouped

into the two wings, allowing long-term flexibility in scheduling, while

making 5 distinct hallway areas per floor allowing for the creation of

academic identities and clusters when desired.

The individual classroom is well defined, with an average occupancy

of 20 students, a smart board, white boards and tack surfaces, and a

‘mini-lab’ with several computer stations allowing for technological

flexibility. The 2:3 proportion allows for flexibility of instructional layout

and balances efficiency of daylighting and envelope area. The number

of classrooms is predicated on a utilization rate of 5/7 per School

Board policy, allowing most classrooms to be assigned to a single

teacher and allowing subject personalization of each room.

Careful attention will be paid to the acoustics in the classroom, both

sound transfer and clarity of speech. The partitions between the

classrooms and the hallway will extend above the ceilings to the floor

above, and will exceed requirements for noise reduction between

spaces. The highly efficient HVAC system will provide a quiet and

thermally comfortable atmosphere, and each room will be generously

supplied with data and power.

TYPICAL LAB &SCIENCE CORE

All 16 science labs are clustered in a distinct wing, giving them bothan architectural identity on the exterior of the school and the interior.This emphasizes the importance of this program in equipping studentsfor the 21st Century. As an increasingly important aspect of curricula,the Science Wing will function not only as a hub for the sciencedepartment but each floor of the Academic Wing as a whole. Thisclustering will facilitate collegial interaction between faculty andstudents, particularly in the gathering nodes along the science hallway.This allows for providing the multiple utility services and ventilationducting required for a modern science lab in an efficient manner.

The science labs will be specially equipped and laid out per theirindividual discipline. The Earth/Space Science labs will be built for

These islands will be arranged so the students can observethe demonstration table while repeating the experiments at their ownstations. The Physics and Earth/Space labs will feature movable labtables to maximize the ability to accommodate various configurations.Each lab will be fully equipped with data display and access technology,as well as safety, gas, water and waste disposal utilities. All labs willshare prep rooms, and there will be a centralized Chemical room toensure secure and safe storage and distribution of materials.

PHASING SUMMARY

PHASING

The existing school and free standing aquatics building will remain

open and occupied until the new facility is complete. Upon transfer of

functions to the new facilities, the old school will be demolished, the

site re-graded and the new athletics fields constructed.

This phasing concept could include early completion and occupancy

SECTION 5

of the Aquatics Center, as shown in Option

B, allowing earlier demolition of the

existing pool building prior to completing

the rest of the school. This would simplify

sheeting and shoring issues involved in

building the new athletic wing in close

proximity to the existing pools.

If the geo-thermal mechanical alternate is accepted, well fields will be

placed under the new athletics fields and parking lots. To meet the

number of required wells for the geothermal HVAC system, it will be

necessary to place some well fields in areas occupied by the existing

school and aquatics buildings, requiring phasing beyond occupancy

of the new school. See the MEP narrative for more detail.

A temporary parking and transportation phasing plan will be developed

in the following phases of design.

At the conclusion of the Feasibility Phase, the Arlington School Board approvedthe Educational Specification, which included a detailed space program for thenet square footage of the building. This was developed from the Arlington Standardhigh school space program, and from information gathered in an extensiveseries of interviews with staff, department heads and faculty, and throughconsultation with the BLPC. The approved Wakefield Ed Spec space programdiffered from the Arlington Standard space program in several minor ways. Ithas more general classroom and dedicated instructional spaces, and fewerspecialty / elective spaces to make the program better fit the unique conditionsof Wakefield.

In the Schematic phase, Bowie Gridley Architects refined the requirements ofthe various programs further in a series of meetings with faculty and departmentheads. Adjustments were made to the distribution of space within somedepartments, increasing some intra departmental spaces while decreasingothers, with the goal of maintaining a total departmental net area equal to thatapproved by the School Board. An example of this would be the Art department,which adjusted the relative sizes and functions of its three art lab spaces,making one lab larger, while another lab was reduced. In some other instancesit was decided to make increases over the Ed Spec space allotment when theissue was critical to Wakefield. An example was the increase in size of thePrincipal’s office to both allow direct access from the hall and a comfortableseating area in addition to the desk. Overall, the goal was for any space toremain within a 5% variance of the Ed Spec program, as specified by ArlingtonPublic Schools standards.

As shown in the summary, the total net variance of the Schematic Design fromthe Ed Spec is an increase of 1%. The three main category divisions of Support,Core, and Specialty / Electives all range from a minus 3% to a plus 5% variancein their subtotals. This demonstrates compliance with the 5% variance limit,although some smaller suites or individual rooms vary by larger percentages.

The variance from the informal goal established in the Feasibility phase of a66% Net / Gross ratio was 4.5%, resulting in a Schematic Design Net/Grossratio of 61.5%.

SUMMARY OF PROJECT COSTSECTION 7PROJECT COST SUMMARY

Downey and Scott, LLC has prepared a schematic estimate of the

Construction Costs of the Wakefield High School Schematic Design.

This estimate includes detailed site and building costs, including

demolition and temporary facilities and pathways etc., as well as

contingency factors for unforeseen design and construction elements

not fully accounted for in Schematics. These hard construction costs

are approximately $87 million in 2009 dollars. See estimate below.

In addition to these Construction Costs, there are several other

expenses which the Arlington Schools must pay to successfully execute

the project, including all design and project management fees, the

various general costs not born by the construction contract, and the

movable furnishings and equipment provided by the school system.

Inclusive of these, the total Project Cost for Wakefield in 2009 dollars

is estimated to be roughly $105 million.

The 2008 CIP estimated the Wakefield Project Costs, for Bid in 2013,

as $169, 253,000. This estimate was based on the market conditions

of that time, and an assumed escalation factor of 5% per annum.

Major economic fluctuations occurring between the 2007 Feasibility

Report and 2009 Schematic Report, and their significant effects on

the construction industry, create some divergence between the two

estimates, and show the difficulty of precise forecasts of future costs.

However, the Schematic costs range fits comfortably within the

Feasibility estimate, and the Alternates provide flexibility for meeting

the 2008 target under varying market forecasts. The design is

consistent with the approved net area of the Educational Specification

for Wakefield, and is comparable in gross area, amenities, and finishes

to Washington Lee and Yorktown High Schools. This estimate

reasonably demonstrates that the Schematic Design is within budget

and meets equity goals established by the School Board.

The anticipated schedule for the construction of Wakefield is for bidding

in 2013, and completion of construction and occupancy in fall of 2016.

It is therefore necessary to escalate the current estimated costs to

anticipate inflation and changes in the marketplace. However, recent

large changes in the economy demonstrate the difficulty of predicting

such future conditions, therefore the projected project costs are

presented here as a range of possibilities. Depending on the aggregate

escalations used, the projected Project Costs for Wakefield when bid

in 2013 could range from a low of $119 million (at an average escalation

of 3%) to a high of $167 million (at an average escalation of 11%).

Historically, an average escalation of 6% per year has been an industry

standard for estimates in this region, as highlighted below.

In addition to the base Construction Costs, a number of Alternates

were considered and their costs estimated. These included both

sustainable technologies and various community amenities, and are

estimated to cost $6 million in 2009 dollars. If these Alternates

accepted, the projected 2013 Bid Project Costs would range from

$126 million to $177 million.

LEED NARRATIVE

Green Building OverviewArlington Public Schools is committed to being a steward of itsenvironment. The construction of Wakefield High School has beentargeted to achieve Leadership in Energy and Environmental (LEED®)certification upon completion. The Arlington Public Schools have askedthe design team to identify the sustainable components appropriatefor this project. Bowie Gridley Architects retained Sustainable DesignConsulting to evaluate the potential environmental performance ofWakefield High School and to make recommendations for additionalconsideration.

The LEED Green Building Rating System is a voluntary, consensus-based national standard for developing high-performance, sustainablebuildings. LEED provides a complete framework for assessing buildingperformance and meeting sustainability goals. Based on well-foundedscientific standards, LEED emphasizes state of the art strategies forsustainable site development, water savings, energy efficiency,materials selection and indoor environmental quality. LEED recognizesachievements and promotes expertise in green building through acomprehensive system offering project certification, professionalaccreditation, training and practical resources.

LEED for New Construction and Major Renovations (LEED-NC) is agreen building rating system that was designed to guide and distinguishhigh-performance commercial and institutional projects, with a focuson office buildings. This project will be submitted under version 2.2(LEED-NC v2.2.), which allows a maximum of sixty-nine credits in sixcategories. To achieve LEED-NC v2.2 Silver certification, projects mustmeet the requirements of thirty-three credits and seven prerequisites.

The following is a brief summary of the efforts required by ArlingtonCounty and Arlington Public Schools to develop a LEED-NC Silverproject:• LEED Registration Fees: Provide the design review fee of $8,450and the construction review fee of $3,380.• SSc4.3: Document the number of students who ride hybrid

busses (similar to Reed School and Yorktown HS).• WEc3: Provide low-flow plumbing fixtures for the school.• EAc3: Select a commissioning agent for enhanced com-missioning services and devlop the Owner’s Project Re-quirements (OPR).• MRp1: Determine the recycling needs of the project.• MRc3: Determine the quantity of reused furniture for theproject.• MRc7: Consider FSC certified wood for flooring, caseworkand doors.• EQp2: Document, via LEEDonline, the no smoking prerequisite• EQc3.2: Provide IAQ testing as part of the base contract.• EQc6.2: Provide temperature controls in each classroom.• EQc7.2: Develop a thermal comfort survey, to be conducted

after occupancy.• IDc1.1: Develop a User Education Program (similar to Reed

ES).• IDc1.2: Develop a Green Housekeeping Program (similarto Reed ES).• IDc1.4: Develop a Joint Use Agreement for Arlington Countyuse of the classrooms, library, auditorium, & pool).

Summary of Green Building RecommendationsThe following analysis outlines the efforts required by APS to developa LEED-NC Silver project.

1. Registration FeesLEED certification provides independent, third-party verification that abuilding project meets the highest green building and performancemeasures. All certified projects receive a LEED plaque, which is thenationally recognized symbol demonstrating that a building isenvironmentally responsible, profitable and a healthy place to live andwork. The LEED certification process consists of two reviews: one atthe end of the design phase, the second at the end of the constructionphase. The US Green Building Council requires payment prior tocommencing the Design and Construction Reviews. Based on a338,000 square foot building, the Design Review fee is $8,450 and theConstruction Review fee is $3,380.

2. Sustainable SitesGreen buildings should minimize the impact of placing a building on asite, with an eye to land use compatibility and biodiversity. Greenbuildings channel development to developed areas with existinginfrastructure, rehabilitates damaged sites, and reduces impacts fromautomobile use. Green buildings optimize microclimate and minimizeeffects on neighboring sites of light, runoff, pollution, etc. SDCrecommends the following actions to capture three Sustainable Sitescredits.

SSc4.3: To capture the fuel efficient vehicle credit, a minimum of 15%of the building’s total population must use alternative fuel school buses.Based on an estimated building population of 1,600 students, APSmust document that at least 240 students arrive via hybrid schoolbusses. The documentation should verify that the minimum blendconcentration is B20 (20% biodiesel, 80% regular diesel).

3. Water EfficiencyGreen buildings seek to reduce the need for potable and waste waterinfrastructure as well as recharging the local aquifer.WEc3: Up to three points can be achieved by installing water-efficientplumbing fixtures in the building. To capture one water use reductioncredit, the proposed plumbing fixtures must save 20% of the buildingwater use when compared to standard fixture selection, and 30%savings to achieve 2 points. An innovation in design point is awardedfor 40% water savings. SDC recommends installing the following water-saving fixtures to achieve a savings of 41% and capture three LEEDpoints:• Dual-flush water closets in all restrooms and gang toilets• Waterless urinals in the male gang toilets• Low-flow lavatories in all restrooms and gang toilets• Low-flow shower heads• Low-flow sinks in the classrooms

4. Energy and AtmosphereGreen buildings should ensure that the buildings systems function asintended, establish energy efficiency and optimization for the buildingenvelope and systems, encourage use of renewable and distributedenergy systems, and support early compliance with the MontrealProtocol for ozone protection.

SECTION 8



EAc3: A commissioning agent has not yet been selected. In order tocapture a point for enhanced commissioning, the commissioning agentmust provide two drawing reviews prior to bid.

5. Materials and ResourcesGreen buildings reduce waste from construction and building occupantsand redirects recyclable material back to the manufacturing process.They extend the life cycle of existing building stock, in part by extendingthe life cycle of targeted building materials. They increase use of buildingproducts with recycled content material and of locally manufacturedbuilding products. They reduce depletion of finite raw materials andencourage environmentally responsible forest management.MRp1: A designated area for recycling must be provided in order tocomply with the LEED Materials and Resources Prerequisite. A 500SF recycling room is recommended.MRc3: A point can be earned if salvaged, refurbished or reusedmaterials constitute at least 5% of the total value of materials on theproject. Determine if used furniture will be used on the project andwhat the value of the furniture would be if purchased new.MRc7: One point can be earned for incorporating FSC Certified woodinto the building. SDC recommends considering including an alternatefor FSC certified wood flooring, casework and doors.

6. Indoor Environmental QualityGreen buildings should promote indoor air quality (IAQ) and preventexposure to environmental tobacco smoke (ETS). Green buildingsprovide a high level of individual occupant control of thermal, ventilation,and lighting systems. They provide a connection between indoorspaces and the outdoor environment through the introduction of sunlightand views into the occupied areas of the building.EQp2: Smoking must be prohibited on school property.EQc3.2: A point can be achieved by developing and implementing anindoor air quality management (IAQ) plan for the preoccupancy phaseof the project. SDC recommends conducting baseline IAQ testingafter construction and prior to occupancy. The tests must demonstratethat the contaminant maximum concentrations listed below are notexceeded.

• An educational outreach program or guided tour could bedeveloped to focus on sustainable living, using the project as anexample. To document the tour, APS will need to develop a brochureor handout highlighting the green elements of the project.• A manual, guideline or case study to inform the design of otherbuildings based on the successes of this project. This manual will bemade available to the USGBC for sharing with other projects. Thiselement is normally achieved by including the project into the DOEHigh Performance Buildings database (for examples see http://www.eere.energy.gov/buildings/database/ ).IDc1: To capture the Green Housekeeping Innovation Credit, APS willneed to adapt their standard green housekeeping plan (currently beingdeveloped for Reed ES) to meet the needs of Wakefield HS. Thehousekeeping program will need to incorporate all of the followingelements:• A statement of purpose describing what the policy is trying toachieve from a health and environmental standpoint, focusing oncleaning chemicals and custodial training at a minimum.• A contractual or procedural requirement for operations staff tocomply with the guidelines, including a written program for trainingand implementation.• A clear set of acceptable performance level standards by whichto measure progress or achievement, such as Green Seal standardGS-37 (see www.greenseal.org) or California Code of Regulations, Title17 Section 94509, VOC standards for cleaning products (go towww.calregs.com, click on ‘California Code of Regulations’ and performa keyword search for ‘94509’). Concentrated cleaning products shouldbe utilized when available.• Documentation of the program’s housekeeping policies andenvironmental cleaning solution specifications, including a list ofapproved and prohibited chemicals and practices. Demonstrate thatthe products used in the project are non-hazardous, and have a lowenvironmental impact.IDc1: To capture the Joint Use Agreement Innovation Credit, APS mustdocument their agreement with Arlington County to share use of schoolfacilities such as the play fields, classrooms, library, auditorium, &pool.

Chemical Contaminate

• Formaldehyde• Particulates (PM10)• Total Volatile Organic Compounds (TVOC)• 4-Phenylcyclohexene (4-PCH)• Carbon Monoxide (CO)

Maximum Concentration

50 parts per billion 50 micrograms per cubic meter 500 micrograms per cubic meter 6.5 micrograms per cubic meter 9 parts per million & e” 2 ppm above outdoor levels

EQc6.2: One point is awarded if individual comfort controls(thermostats) or operable windows are provided for 50% of the buildingoccupants and if comfort controls are provided in each shared multi-occupant spaces including classrooms.EQc7.2: Implementation of a thermal comfort survey within 6 to 18months after occupancy will earn one point. SDC recommendsperforming this survey as a means to provide the optimal working andlearning environment for students and teachers. The survey will alsoprovide insight as to the effectiveness of the installed energy systems.Adjustments made based on survey responses have the potential tosave energy and money.

7. Innovation in DesignLEED provides a separate category of points for exceptionalperformance above the requirements set by the LEED-NC GreenBuilding Rating System and/or innovative performance in Green Buildingcategories not specifically addressed by the LEED-NC Green BuildingRating System. SDC recommends pursuing the following innovationcredits: Green Educational Program, Green Housekeeping Plan, andJoint Use Agreement.IDc1: To capture the Green Educational Innovation Credit, SDCrecommends that APS determine who at APS will be primarilyresponsible for developing the program. SDC will work with that individualto ensure that the credit requirements are met. The user educationprogram developed for REED SCHOOL can be used as a guide.Specifically, two of the following three elements must be incorporatedinto the education program:• A comprehensive signage program built into the building’s spacesto educate the occupants and visitors to the benefits of green buildings.The signage scope will need to be developed prior to issuing the projectfor construction.

Basic Seismic force resisting system: Steel system not neces-sarily detailed for seismic resistance.Analysis Procedure: Equivalent lateral force procedure.

4. Minimum frost depth = 30 inches.

C. Foundations:The foundations will consist of a spread footing foundation s y s t e mbearing on natural soils or new compacted fill for support of theproposed building. Maximum cuts and fills of about 20 feet and 5 feet,respectively, will be required to reach design subgrades based on theproposed site development plan. The new compacted fill should be ofsimilar compressibility as the upper portions of the natural soils.Therefore, based on preliminary recommendations from thegeotechnical engineer, the spread footings shall be designed for anallowable bearing pressure of 3,000 psf.

The main gymnasium floor (Level 0) will be at an elevation 15 feetlower than the main ground floor level of the school (Level 1). Theelevation difference will require earth retaining basement/ foundationwalls. These walls will be reinforced concrete walls spanning betweenthe floor levels and inter-connecting to a wall bracing system to

distribute the lateral soil pressure to the foundations. The lateralpressure from the water in the pools may also require some retainingstructures transitioning to the lower level of the gymnasium.The slab on grade will consist typically of 5 inches of concrete reinforcedwith welded wire fabric. This thickness may increase in areas suchas the natatorium and auditorium.

The existing pool building immediately adjacent to the site will remainin operation until occupancy of the new school and pool, so anexcavation retention system will be installed before excavation for thebelow grade gymnasium and locker rooms.

D. Structural Steel Framing System:

Classrooms and Offices:The structural system was selected in response to the typicalclassroom bay size consisting of two 32 foot classrooms divided by a15 foot hallway, spaced at 24 feet along the main classroom wings,with slightly larger spans in the science wing. The requirement oflarge column-free spaces in lower floors necessitates the use of columntransfers in several locations, which are kept to a minimal depth bylightweight construction. The proposed structural system is acomposite slab on metal deck with composite steel beams. Thissystem will minimize the total building weight, resulting in optimalcolumn transfer girder depths, and footing sizes. The repetitiveclassroom bays present the added benefit with steel of allowing theuse of repetitive member sizes, and takes advantage of uniformity indetailing, fabrication, and erection.Long span members will be cambered to control the total deflection,and floor vibrations will be limited to no greater than a “slightlyperceptible” level as defined by the AISC Steel Design Guide for FloorVibrations Due to Human Activity. The framed floors will be 3 ¼” oflight weight concrete on 2" deep, 20 gauge galvanized composite steeldeck for a total thickness of 5 ¼”. This slab assembly provides a 2 hr.fire rating without any applied protection. The steel beams and columnsrequire fire protection.

BUILDING SYSTEMS

Pool and Gymnasiums:The long span roof of the pool and gymnasium will consist ofapproximately 10 foot deep (out to out) steel trusses spaced at roughly35’ on center with infill bar joists. A fire rated roof assembly is notrequired in these spaces where the ceiling is more than 20ftabove the floor. Due to the varying roof heights of the Pool, Gymnasiumand Auxiliary Gymnasium, all four sides of each space will requiresupport for lateral loads in the form of at least one braced frame bayextending from the foundations to the roof.

Bracing and Fire Protection Systems:The lateral load systems will typically consist of concentrically bracedframes symmetrically placed around the center of mass of the building,and extending from the foundations to the roof. All of the bracedframes will be located within the partition walls of the building, with atleast two in the transverse direction and two in the longitudinal direction.The lateral loads imposed on the building are collected at each framedlevel and transferred to the braced frames through the concrete floor,which serves as a rigid diaphragm. Masonry shear walls could beused as an alternative lateral bracing system in the administrative andclassroom portions of the building, however the need to have themasonry contractor on site during the steel erection may prove morecostly to schedule and coordinate. Due to the height of the gymnasiumand natatorium spaces, masonry walls are not a workable alternativefor bracing those areas. In fact, tall masonry building façade walls willrequire a bracing structure to resist wind and seismic loadings actingnormal to the wall surface.

Expansion joints will be detailed between the classroom building andthe administrative and athletic wings of the building. There is also arequirement to divide the complex into three fire zones using fire wallswith separation of structure at those walls. Depending on the locationof these fire walls, an additional expansion joint may be required toreduce the total length of any one individual structure. This effectivelycreates three or more independent structures, each with its own lateralload resisting system. Because the buildings will be built as individualstand alone structures, the design and construction teams have theability to phase construction, although the foundation system wouldlikely be shared by adjoining building divisions.

B. Baseline HVAC System Design:

1. Heating System:The occupied areas of the building will be heated by gas-firedmodulating hot water boilers and a primary/secondary hot water pipingsystem. Multiple modular boilers will be sized to accommodate thecalculated building heating load. Heating hot water will be supplied at180 deg. F and the system hot water coils will be selected based ona 30 deg. F temperature drop. Each boiler will have a wet rotor circulatorwith integral check valves serving the primary hot water loop. Theprimary loop will be connected to the secondary hot water loop througha Low-Loss header. The secondary hot water loop will deliver hot waterto the heating coils in the air handling units, the VAV terminal boxheating coils, and the unit heaters and duct coils. A base-mounted,end-suction centrifugal pump will circulate the water in this loop, andwill be backed up by a 100% standby pump. The secondary pumpswill be equipped with variable frequency drives to reduce pump speedand energy usage when heating demand is low. All heating coils willbe equipped with 2-way valves to allow for variable flow. The heatingsystem will be housed in the Main Mechanical Equipment Room,located at the basement level beneath the Science Wing. Schematicload estimates indicate a Heating Plant capacity of approximately8,750 MBH at a hot water flow of 590 GPM.

2. Cooling System:The building will be cooled by three water-cooled centrifugal chillersand a primary/secondary chilled water piping system. Heat from thechillers will be rejected to a multi-cell induced-draft, counter-flow coolingtower located on the Science Wing roof. Chilled water will be suppliedat 44 deg. F and the system chilled water coils will be selected basedon a 12 deg. F temperature rise. Each chiller will be served by adedicated end-suction centrifugal pump feeding into a primary chilledwater loop. The primary loop will be connected to the secondary chilledwater loop through a Low-Loss header. The secondary loop will deliverchilled water to the cooling coils in the air handling units, as well asany necessary fan-coil units or duct coils. A base-mounted, end-

suction centrifugal pump will circulate the water in this loop, and willbe backed up by a 100% standby pump. The secondary pumps willbe equipped with variable frequency drives to reduce pump speed andenergy usage when cooling demand is low. All cooling coils will beequipped with 2-way valves to allow for variable flow. The cooling systemwill be housed in the Main Mechanical Equipment Room. Schematicload estimates indicate a Cooling Plant capacity of approximately1,500 Tons, requiring (3) 500 Ton Chillers. Estimated chilled waterflow will be 3,000 GPM. Estimated condenser water flow will be 4,500GPM.

3. Variable Primary Chilled and Condenser Water FlowThe possibility of utilizing VFDs on the primary chilled water andcondenser water pumps to increase chiller efficiencies and reducepumping energy will be evaluated at the Design Development Phase.

4. HVAC Equipment:All occupied areas of the building will be air conditioned exceptstairwells, janitor closets, electrical closets and mechanical equipmentrooms. Modular Rooftop Air Handling Units (AHUs) will provide primaryair, via a medium-pressure duct system, to fan-powered (classrooms)and shutoff VAV terminal boxes serving the individual spaces. Air willbe distributed downstream from the terminal units through low-pressureducts. The VAV terminal units will be equipped with hot water heatingcoils.

Large single-zone spaces such as Auditoriums and Gymnasiums willbe served by constant-volume units that distribute air via low-pressureduct systems.

Code required ventilation will be provided through the air handling units.Occupancy calculations and outdoor air quantities will be based onthe minimum required by the current edition of ASHRAE 62 or theamount required to maintain the proper pressure relationships in theareas served, whichever is greater. Additionally, CO2 sensors will beinstalled in the classrooms and other high-occupancy spaces to allowfor reduced outdoor air volumes when the spaces are either empty orpartially occupied.

The AHUs will have double wall construction with 1 inch, 3-lb./cf. densityfiberglass or foam glass insulation. The fan/motor assemblies will bemounted on an internal restrained spring isolation base. The unitcabinets will be mounted on roof curbs with spring vibration isolationrails.

The minimum supply air temperature for air handling systems will be50°F db.

See Drawing M2.1 for a preliminary layout of Rooftop Air HandlingUnits (AHUs).

6. Natatorium:The Natatorium will be served by a roof-mounted, packaged DX PoolDehumidification unit. A heat exchanger will be provided in the unit toutilize hot gas for pool water heating. When pool water heating is notrequired, heat from the dehumidification process will be rejected tothe outdoors via an air-cooled condensing unit. Supplemental heatingwill be provided by a natural gas furnace. The unit will include anexhaust fan sized to maintain the Natatorium at a slightly negativecondition to the surrounding areas of the building.

7. Main Locker Rooms:The Main Locker Rooms will be served by a roof-mounted, 100%Makeup air unit with an enthalpy energy recovery wheel. All air fromthe Locker Rooms will be exhausted through the wheel to pretreat theincoming outdoor ventilation air. Additional heating and cooling will beprovided by hot water and chilled water coils served from the buildinghydronic systems.

9. Preliminary Natatorium Unit Size:a. Natatorium – 22,000 CFM and 50 Tons Cooling

C. Alternate HVAC System Design – Geothermal Heat Pumps:

1. Heating & Cooling System:The occupied areas of the building will be heated and cooled by water-source heat pump units with integral, water-cooled compressors.These units will be connected via a primary/secondary condenser waterloop to four geothermal well fields. Condenser water for each field willbe circulated by a secondary, base-mounted centrifugal pump, locatedin a basement Well Field Pump Room and backed up by a 100%standby pump. Each of these secondary Well Field loops will feedinto a primary condenser water loop circulating within the building.The primary loop will also be served by a base-mounted centrifugalpump, backed up by a 100% standby pump. Pumps and equipmentserving the primary loop will be located in a Main Mechanical EquipmentRoom at the basement level beneath the Science Wing. Estimatedtotal flow in the well field loop will be 4,500 GPM.Locations for the Well Field Pump Rooms may be found on theArchitectural floor plans.

2. Geothermal Well Fields:Preliminary load estimates indicate a peak cooling load ofapproximately 1,500 Tons. Assuming 400 ft. deep wells at an averagecapacity of 3.2 tons per well, a total of 460 wells will be required toaddress this load. These wells will be spaced on 20 foot centers andpreliminary site layouts indicate four separate fields will be required.

Field #1 will be located under the Parking Loop at the southeast endof the new building. Field #2 will be located under the New Practice &P.E. Field on the east side of the building. Field #3 will be locatedunder the open area on the northeast side of the building and Field #4will be installed beneath the Parking area and the western edge of theNew Baseball Field after the existing school is demolished.See Drawing M3.1 for preliminary Well Field locations.

3. Temporary Hybrid System Alternate:Because Well Field #4 will be located partially within the footprint ofthe existing building, it may not be possible to phase construction sothat the cooling loads for the new building can be met while the existingbuilding is demolished and the fourth Well Field is constructed. If thatproves to be the case, it will be necessary to create a temporaryhybrid geothermal system by installing a cooling tower to rejectadditional heat from the loop until Field #4 is completed and broughton-line. The cost of this temporary arrangement needs to be includedas a sub-alternate to the Geothermal Heat Pump System Alternate.Preliminary load calculations indicate the tower would need to addressapproximately 525 Tons of cooling at around 1,260 gpm of flow.Equipment costs should include an induced-draft, counter-flow towerwith a separate condenser water pump and a plate-frame heatexchanger to separate the open tower system from the closedgeothermal loop.



4. HVAC Equipment:All occupied areas of the building will be air conditioned exceptstairwells, janitor closets, electrical closets and mechanical equipmentrooms. Classrooms, offices, small meeting rooms, toilets and corridorswill be heated and cooled by individual Geothermal Heat Pump Units(HPUs) located either above the corridor ceilings or in small closetsaccessed through a door from the corridor. Multiple Packaged RooftopHeat Pump Units will provide heating and cooling to the larger, high-occupancy spaces

Code required ventilation will be provided to the classrooms, officesand other smaller spaces by Dedicated Outdoor Air Supply (DOAS)heat pump units located on the roof. These DOAS units will supply100% outdoor air at neutral conditions either directly to the occupiedspaces or to the return connections of the individual interior heat pumpunits.

LANDSCAPE NARRATIVE

General Description of Site and Landscape Improvements

The general design concept for the project is to replace or maintain-in-place the existing school buildings, sports and recreational facilities,and site support facilities such as parking and service. The proposedproject also includes, as alternates, additional site facilities requestedby Arlington County and community organizations, as well as publicinfrastructure improvements, such as streetscapes, required byArlington County as part of the modified use permit process.

The project will be phased to keep the existing school buildings inoperation while the new facilities are being constructed, and to alsokeep open existing sports and recreational facilities during construction,to the maximum extent possible.

The general arrangement of the site will consist of the following:

- a new school building, including athletic facilities and pool,constructed on the existing sports fields on the west site of the site

- new baseball and softball fields, including general recreationalspace, constructed on the existing school building site on the eastside of the site.

- a new main parking lot in the center of the site, adjacent to S.Dinwiddie Street, for school and recreational fields parking.

- maintenance of the existing stadium field and track, existing tenniscourts, and existing sports fields north of the existing school.

- new streetscapes, consisting of sidewalks, street trees, lighting,and curbside parking, along the portions of S. Dinwiddie Street, S.Chesterfield Road, and S. George Mason Drive that are adjacent toother proposed new work.

Vehicular Access and Parking

Vehicular access to the site will be from existing public roads, asfollows:

- The main vehicle entrance to the site will be from S. Dinwiddie

Street into the main parking lot via a one way road in and one wayroad out . This lot will contain 236 car parking space, includingdesignated handicapped spaces. There will be a two lane wide, oneway bus loop separate from and outside the parking lot for bus pick-up and drop-off. The bus loop can accommodate the16 required bussesstaged for afternoon pick-up without interfering with parking lot access.The bus loop can also be used for single side curbside parking duringevenings and weekends. The exit for this entrance will align withexisting S. 14th Street, immediately to the south across S. DinwiddieStreet.

- A secondary vehicle entrance to the site will be from S. ChesterfieldRoad, at the same location of an existing entrance across from S.Buchanan Street. This entrance will lead to 24 new convenienceparking spaces, including designated handicapped spaces, for accessto the recreational fields adjacent to S. Chesterfield Road. The roadwill also lead down to the existing stadium and tennis courts formaintenance access. Three additional designated handicappedspaces will be provided for the tennis courts at the end of this road.

- Service vehicle access to the school will be from a vehicularaccess road off S. George Mason Drive. This service road canaccommodate the various size delivery trucks that come to the school.The service area at the west side of the school will contain a servicecourt in which the service vehicles can turn to back into a loading areaand also turn around to exit via the same service road.

- Total parking on the site will consist of 236 spaces in the mainparking lot, including 8 handicapped designated spaces; 27convenience spaces adjacent to the service road from S. ChesterfieldRoad, including 4 handicapped designated spaces; for a total of 263spaces on site. The existing school site has 233 parking spaces

- Total curbside parking adjacent to the site will be 97 spaces(including 4 designated handicapped spaces. The existing site has87 curbside spaces.

- 32 additional overflow spaces are available as curbside parking inthe bus loop during evenings and weekends.

Pedestrian Access and Building Entrances

Pedestrians will have access to the new building via paved concretewalkways from the public sidewalk system that parallel adjacentroadways, and also from walkways from site parking lots.

Pedestrians will enter the building at three main building entrances,as follows:

- The main entrance to the school on S. Dinwiddie Street will frontdirectly on a new public sidewalk. This entrance will have broad stairsas well as grade accessible 8' wide sidewalks leading to an outdoorentrance plaza.

- At the student entrance and athletic entrance to the school fromthe main parking lot there will be a 15' minimum width sidewalk leadingfrom the public sidewalk on S. Dinwiddie Street to the entrance doors.There will also be an entrance plaza leading from the main parking lotto these entrances. This entrance plaza will cross the bus loop atwalkway grade, and will have bollards to separate the adjacentsidewalks from the bus lanes.

- At the S. George Mason Drive entrance to the school, there willbe a paved entrance plaza. Access to this entrance plaza will be fromthe public sidewalks along S. George Mason Drive, either from thenorth via a paved 8' wide concrete sidewalk or from the west via stairsdown from S. George Mason Drive. An 8' wide accessible route fromthe sidewalk west of the entrance plaza will loop down to meet thesidewalk coming into the site from the north.

In addition to the three main entrances, there will be access from theathletic facilities inside the building to the adjacent fields through alower entrance on the north side of the building. This access will alsolead to restrooms inside the building that will be available for events atthe stadium.

Pedestrian access to the site facilities will on paved concrete walkwaysfrom the pubic sidewalks that parallel adjacent roadways and alsofrom walkways from site parking lots, as follows:



- Access to the new baseball and softball fields will be on 8' widewalkways leading from the main parking lot on S. Dinwiddie Streetand the convenience parking lot on S. Chesterfield Road. Thesewalkways will be accessible routes to the fields and through the siteand open for public access.

- Access to the stadium will be from a new 10' wide accessiblewalkway from the main parking lot on S. Dinwiddie Street down to anentrance to the stadium north of the new school building. This walkwaywill also provide an occasional service vehicle route to the lower athleticbuilding entrance. There will be a new 8' walkway south of the existingstadium to allow spectators to move around the field to the grandstandson game days.

- Access to the existing tennis courts will be from a new 8' wideaccessible walkway from the adjacent handicapped designated parkingspaces, via a new 8' wide walkway adjacent to the stadium accessroad, and via new 8’ wide stairs from the walkway through the siteadjacent to the baseball and softball fields.

- A new 8' wide accessible route on a paved walkway will bisectthe site north of the new school building. This walkway will allow fullpedestrian access through the site for access to the recreationalfacilities as well as for pedestrians who want to take a short cut routethrough the site.

Public Streetscapes

The project will include development of new public streetscapes alongS. Dinwiddie Street and portions of S. Chesterfield Road and S. GeorgeMason Drive. The streetscape improvements include the following:

- New concrete curb and gutter

- New concrete driveway entrances for all vehicle crossings atsidewalks

- Accessible route ramps and crosswalk markings at all streetcrossings

- Curbside parallel parking spaces, including designed handicappedspaces.

- Street trees at approximately 35' on center. At areas adjacent tothe recreational fields these trees will be in continuous 5.5' widecontinuous tree panels; at areas adjacent to the school the streettrees will be in 6' wide by 12' long tree boxes.

- Concrete sidewalks with a minimum clear dimension of 10' wide.

- Arlington County ‘Carlyle’ street lights at approximately 100' oncenter.

BUILDING SYSTEMS

- A new practice field will be located in the area between the baseballand softball fields. This field will measure approximately 120' by 80'.

- A new practice and physical education field, approximately 160'by 75', will be located adjacent to the athletic wing of the building.This field will be used for various athletic programs, and can also beused as a team warm up space or reception space on game dayswhen the stadium field is in use.

Building Courtyards

The project includes three outdoor courtyards for the new schoolbuilding.

At the student entrance to the school from the main parking lot therewill be a demonstration rain garden courtyard. This courtyard willfunction as part of the project’s storm water management system,but will also be used to demonstrate the storm water managementprinciples in practice. An upper part of the rain garden will contain acollection and infiltration basin with trees, shrubs, and ground coversto demonstrate upland planting and runoff. Overflow from this upperbasin will flow and fall into a lower collection area with trees, shrubs,and ground covers and primarily demonstrate lowland planting andinfiltration. A boardwalk will bisect the area so students can movethrough the rain garden area, and this boardwalk will also providemaintenance access. It is anticipated that Wakefield science classeswill utilize the rain garden as a teaching tool.

The town square courtyard in the center of the new building will providean outdoor seating and eating plaza for students and staff. Thecourtyard will be primarily paved, with a perimeter planting of ornamentalgrasses and native shrubs. Tress will shade the courtyard paving.Seating will be provided on ‘C’ shaped seat walls where students cangather and face either in or out; on benches at the courtyard perimeter;and on dining tables and chairs.

The theater courtyard will be in the center of the classroom portion ofthe school and will have amphitheater style seat walls for student

instruction or performance; a small terrace for special functions andtheater event break-out space; and a small wet pond for aquaticgrasses, plants, and other fauna. The wet pond will be used by theschool for science instruction and have a recirculating pump to providewater movement and white noise for the courtyard.

Site Furnishings

Furnishings on the site will include bicycle racks, benches, trashreceptacles, and flagpoles.

Benches will be 6' length metal strap benches with backs and armrests. Trash receptacles will be metal strap construction with topsand liners. Both benches and trash receptacles will be located atbuilding entrances, building courtyards, and along walkways throughthe public parts of the site. Flagpoles will be 35' aluminum standardswith internal halyards and be located in the student entrance plaza tothe school and at each ball field. Bicycle racks will be ArlingtonCounty standard metal loop racks and will be located at each of thethree entrances to the school and at each ball field.

Site Lighting

Site lighting will consists of cut-off style luminaires on 25' metal polesfor parking lot and roadway lighting; cut-off style luminaires on 15'metal poles for park walkway and courtyard lighting; and specializedhigh mast lighting for the baseball field and softball field. All parkinglots, roadways, and walkways will be illuminated with site lighting.Site lighting will comply with Arlington County requirements to minimizethe amount of light that is visible from beyond the site.

Landscape Planting and Reforestation

New landscape planting will be installed on the site, consisting ofshade trees along the project’s streetscapes; parking lot shade treesand shrubs to comply with Arlington County standards; shade andornamental trees adjacent to building entrances; shade trees adjacent

to walkways through the site; and screen plantings east of the sportsfields adjacent to S. Chesterfield Road and S. Dinwiddie Street.Additional screen planting will be installed adjacent to the servicearea of the school; adjacent to the tennis courts; and adjacent to theretaining wall north of the tennis courts.

New reforestation will be installed in areas north and east of the athleticportion of the new building. This reforestation will offset the removal ofexisting woodland adjacent to the existing swimming pool building.Other existing woodland north of the proposed new building will bepreserved and protected during construction.

Landscape plant materials and reforestation plant materials will beprovided to meet or exceed Arlington County tree replacementrequirements for the site.

Landscape plant materials will be selected from native and local plantsthat are adapted to the region’s climate and not require permanentirrigation or long term maintenance. An initial one year period of specialmaintenance to establish new plants will be made part of theconstruction contract.

Site Access

All site facilities, building entrances, and destinations on the projectsite have accessible routes, as follows:

- All entrances to the school and swimming pool will have accessibleroutes from adjacent parking lots and public sidewalks.

- ADA parking spaces are provided in all parking lots equal to or inexcess of minimum requirements. ADA parking spaces are distributedthroughout the site in all parking areas.

- The school courtyards are accessible from the buildings.

- Sports and recreation areas on the site can be reached viaaccessible routes

- Walkways through the site are accessible



CIVIL NARRATIVE

General Description of the Site and Requirements:

The existing Wakefield High School is located at 4901 S. ChesterfieldRoad, Arlington, Arlington County RPC No. 28017001, at the Northwestcorner of the Intersection of S. Dinwiddie Street and S. ChesterfieldRoad. The Site Area is 1,575,559 Square Ft. or 36.1699 Ac., per theField Survey. The site is zoned S-3A, Special District, which is thezoning generally used for Schools and public facilities in ArlingtonCounty. Within the S-3A zone, Public Schools are a Conditional Use,requiring a Use Permit. In general, the site is surrounded by single-family residential uses, except for an area across S. Chesterfield Roadfrom a small portion of the Eastern property line, where the ClaremontElementary School is located.

The purpose of the project is to replace the existing Wakefield HighSchool with a new, modern, state-of-the-art facility, with the samestudent population, and to assure that the new facilities and site meetall current Arlington County and Commonwealth of Virginia codes andregulations. Improvements to meet current standards will includeupgrades to utility services to provide adequate sewer and water serviceand fire protection, adequate site drainage, and management of stormwater to provide quantity and quality controls for site runoff. In additionto Arlington County standards and regulations, the new facilities willmeet LEED Silver minimum standards.

Since the new facilities must be constructed while the existing facilitiesremain in use by the students and staff, the site will undergo majordisturbance over an extended period of time, to build the new Schoolwhere the existing baseball and softball fields and pool house arecurrently located, move everyone into the new facilities, demolish theexisting old School, and replace the baseball and softball fields in thenewly available space. The existing football field and surroundingbleachers, and the existing tennis courts will be left undisturbed bythe proposed work. The design of the proposed improvements andphasing must take into account that all utility services to the existingSchool must be maintained while the new School is being constructed.

Therefore, new utilities must be constructed to serve the new Schoolbefore the utilities serving the existing School can be disconnected orrelocated.

Storm Drainage and Stormwater Management –County Requirements:

The site is located within the Four Mile Run watershed. In accordancewith current Arlington County regulations, sites developed within thiswatershed must provide stormwater management facilities to captureand detain runoff from the developed site, during a 100-year rainfallevent, and release that runoff into the downstream drainage system ata peak rate no larger than the theoretical peak rate of runoff leavingthe “pre-developed” site during a 10-year rainfall event. Practically,the definition of “pre-developed” is a weighted average of a “meadowcondition site” and the actual existing conditions on the site beforethe planned improvements start. Because of this extreme requirementby the County, the fact that there is actually a reduction in imperviousarea associated with the proposed improvements does not eliminatethe need for stormwater capture and detention facilities. Therefore,stormwater detention facilities must be provided. Because the site isa school site, and all available space is used for building, facilities orathletic activities, or preservation of tree cover to meet other ArlingtonCounty requirements, there is no available space for a pond to collectand detain stormwater runoff. The next most cost-effective availablemethod for capture and containment for detention is large-diameterunderground pipes, either corrugated metal or HDPE, which can beconstructed under the planned parking areas.

In addition, Arlington County has a Chesapeake Bay PreservationOrdinance, and requires capture and quality treatment (BestManagement Practices) of all runoff from vehicular access areas ofthe site, and other impervious areas. Arlington County approves theuse of all Commonwealth-accepted methods of BMP treatment,including vegetated swales, biofiltration basins and various structuralpractices, and also encourages use of innovative practices. Siteconstruction for the new school will include construction of several

types of BMP facilities, including biofiltration basins, vegetated swales,and structural Filterra systems, which are essentially biofiltration unitsin concrete boxes. These facilities will be constructed to capture andtreat runoff from all vehicular access areas of the site and to captureand treat runoff from portions of the new School roof.

Storm Drainage and Stormwater Management –LEED Requirements:

On top of the County requirements, there are also Sustainable Sitegoals for LEED. The Peak Rate of Runoff portion of Sustainable SiteCredit 6.1, for Quantity Control, can be easily met simply by compliancewith Arlington County’s Quantity Control regulation as explained above.The Total Volume of Runoff portion of SS Credit 6.1 is met automatically,as long as the total percent of imperviousness of the site is reducedby the proposed development. Another way to meet that requirementis to capture and harvest the runoff from impervious areas of the site,using the captured water for grey water uses and/or irrigation uses, sothat the captured water never gets back into the stormwater runofffrom the project site. If there is an increase in impervious areaassociated with the planned development, capture and harvest of runofffrom an area equivalent to the increase will meet the SS Credit 6.1.

Sustainable Site Credit 6.2, for the Quality Control and treatment ofstorm runoff, requires that runoff from new impervious areas within theLEED Boundary be captured and treated by systems that will remove80 percent of total suspended solids from the runoff. Compliance withArlington County requirements will meet only a portion of this LEEDrequirement. Additional capture and treatment facilities must beprovided to achieve this credit.

Water Efficiency Credit 1.1 and Credit 1.2 can be achieve by eliminatingthe use of County-provided potable water for irrigation purposes. If anirrigation system is required, then non-potable water must be used forthe system. If an irrigation system is not constructed at all, the pointsare achieved.

BUILDING SYSTEMS

The strategy to meet County and LEED requirements for this projectevolves from these factors:

· Irrigation is required for the new baseball and softball fields.

· Capture and Storage of runoff is required to meet County QuantityControl requirements for Site Plan approval.

· Capture and treatment of runoff is required to meet County QualityControl requirements for Site Plan approval.

Since we must provide irrigation, the water must be non-potable,captured and harvested rainwater. The best source of relatively cleanrainwater is the new School roof. Captured roof water will need lessfiltration and treatment for re-use. Since we must provide storage forcaptured runoff anyway, we can capture and contain the runoff fromthe building roof in an underground holding system, and use that runofffor grey water and irrigation uses. It turns out that capturing andcontaining the first 1-inch of runoff from the building roof will completelymeet the County requirements for Quantity Controls. Therefore weuse the underground containment system as a Cistern, and get doubleuse from the captured rainwater.

And since all runoff from impervious areas must be captured and treatedto reduce Total Suspended Solids to meet SS Credit 6.2, capture ofthe runoff from the new School roof, and elimination of all that runofffrom the storm drainage system, constitutes 100 percent treatment.Doing this, in combination with using biofiltration basins, vegetatedswales and other structural practices to capture and treat runoff fromvehicular access areas should allow us to achieve LEED SS Credit6.2.

Site Utilities – Domestic Water and Fire Protection:

The site is surrounded by 12-inch watermains in South George MasonDrive, South Dinwiddie Street, and South Chesterfield Road. The schoolis served by a connection to the existing main in South Dinwiddie.The results of recent flow tests run by Arlington County indicate that,

although static pressures on the existing system are not very high(about 58 psi), response to flow demand is extremely strong, with anexpected available minimum flow of 3480 gallons per minute at a residualpressure of 20 psi.

New connections to the existing public water mains in the streets willbe constructed to provide domestic and fire protection sprinkler servicesto the new School, while the existing water services to the old Schooland surrounding fire hydrants remain in use during construction. Newfire hydrants will be provided to meet Arlington County Fire Marshallocation and spacing regulations. Domestic water service to the newbuilding will be metered. New domestic water service lines will beextended from the new school metered system to serve the existingconcession stand and future out-buildings.

Site Utilities – Sanitary Sewer:

An existing sanitary sewer main traverses the middle of the site fromSouth Dinwiddie Street, under the football field and out to South GeorgeMason Drive at the northern tip of the site. The 8-inch diameter sewermain, which serves the residential area south of South Dinwiddie Streetas well as a portion of the School site, runs along the west side of theexisting school building and under the western tip of the existing tenniscourts before turning north to run under the center of the football field,paralleling the large storm drainage trunk line. In addition, there isanother sanitary sewer main running under South Chesterfield Roadalong the eastern edge of the site. This main serves the residentialarea along the east side of South Chesterfield Road, as well as theeastern portion of the school. The County has confirmed that theexisting public sanitary sewer systems have sufficient capacity tocontinue to serve the Wakefield High School.

New connections to the public sanitary sewer system will beconstructed for the new school, while the existing connections aremaintained to serve the existing School while it remains occupied.Once the existing school is abandoned, the existing sewer serviceconnections will be demolished and removed back to the sewer mains.

Site Utilities – Gas and Power:

The existing School has a gas service connection to an existing 4-inch gas main in South Chesterfield Road. There are also existinggas mains in South Dinwiddie Street and in South George MasonDrive. The existing gas service is provided by Washington Gas.

The existing 6-inch gas main in South George Mason Drive providesservice to the existing Pool House. It is assumed that WashingtonGas will extend a new gas service from this existing main to serve thenew school. New gas service will be brought to a location in theservice area along South George Mason Drive. Washington Gasextends the service line and will also set the new gas meter.

There is an existing power transformer / switch gear located near theintersection of South George Mason Drive and Dinwiddie Street, onour side of South George Mason. It is assumed that Virginia Powerwill bring the new power feed for the new School from that location.We would assume that the service from the existing transformer to anew transformer, located in the service area of the new School wouldconsist of (4) 6-inch conduits in a concrete duct bank for the primaryrun to the new transformer, and (10) 4-inch conduits for the Secondaryrun from the new transformer to the new School building. The secondaryrun may not need to be concrete encased, but that will have to beconfirmed with Virginia Power.



MUSIC & AUDITORIUM NARRATIVE

Performing arts teaching, production, and performance facilities aregrouped together in a complex near the main entrance to the schooland include an Auditorium and a Black Box Theater and a variety ofspecialized classroom and support spaces. Spaces are organized inthree precincts:

Backstage and Production Spaces are isolated from public areas toallow the Auditorium and Theater to function properly at performancetimes. They include two chorus-size dressing rooms and associatedtoilets along a corridor flanking the house left side of the main theaterauditorium, a small shop and tool storage area, storage spaces forboth theater and music equipment, and a circulation system that allowseasy backstage access between support spaces and both stages.The circulation system also allows easy loading from outside to thetheaters through a dedicated loading door.

Public Spaces include the auditorium of the Main Theater, supportedby a small box office, and public access to the Studio Theater. Otherpublic support spaces, such as public toilets, are organized so thatthey meet general school needs throughout the day when noperformances are taking place. Public lobby space is created bywidening corridors at the first and second floors outside the MainTheater, so that performances are supported with as little dedicatedpublic space as possible for maximum building efficiency.

Music Teaching Spaces are grouped around a main floor corridor. Asystem of doors allows them to be isolated from the public atperformance times, so that music rehearsal spaces and classroomscan serve as primary performance support spaces for the Musicprogram. But the same corridor system allows public access whenneeded to the Studio Theater and easily handles the large groups ofstudents that regularly attend classes and rehearsals in the Musicarea.

A few support spaces are located at the second level, along with accessto the mezzanine seating levels of both theaters.

Design Principles

Several key principles guide the design approach to the performingarts complex. The most important of these include:

Safety:Above all, the safe operation of the theaters and support spaces iscritical. Theaters are inherently dangerous places to work, and justas student safety is crucial in planning physical education spaces orscience labs, so it is vital in academic theater design. Thus all stagelighting mounting positions in the Main Theater are accessible fromcatwalks, rather than via personnel lifts or tall A-ladders. Stage riggingis by means of motorized winches, the safest operating option available.All large scenic and drapery items can be moved into position withthis equipment. Even in the Studio Theater, stage lighting fixturesaround the perimeter of the space can be reached from the gallerylevel, and use of personnel lifts is limited only to areas over the centerof the room. Backstage corridors are wide to permit ease of movementand equipment. Running lights provide safe illumination in all backstageareas during blackouts. There is nowhere that the safety of studentshas been compromised for design purposes.

Efficiency and Flexibility of Use:Every major space in the performing arts complex has multiple uses.Both theaters can be used for music, dance, and dramaticperformances, and of course the Main Theater is intended for largeschool assembly uses of many kinds. Both theaters are intendedboth as teaching and performance spaces, where instruction inperforming arts disciplines takes place on a regular basis. Thesespaces are classrooms, laboratories, and exhibition spaces. The sameapproach is applied to support spaces. The large music rehearsalclassrooms will serve as backstage support space at performancetimes for music ensembles. Conversely, the dressing rooms areconfigured so that when they are not needed for performances theycan be used for seminars in dramatic literature, small rehearsal spacesfor scene work, and even additional music practice spaces for small

ensembles. Control booths for both theaters are large enough toaccommodate students observing the use of consoles and otherequipment. Catwalk areas serve as staging spaces for lightingequipment and for teaching of stage lighting and theater technology.This approach not only allows performance spaces to function optimallyfor teaching in an academic setting, it allows maximum efficiency oflayout and gets the most use possible out of the spaces included inthe ed specification.

General Descriptions of Key Spaces

Auditorium:The Auditorium seats approximately 550 in a configuration that includesa main floor with lower sloped area, cross-aisle, and stepped upperarea; a mezzanine, and seating in side galleries. The galleries help tomake the layout as efficient and intimate as possible and providereflective surfaces for acoustical purposes. This arrangement isdesigned to allow the auditorium to look good when not all seats arefull. For performances that attract only 300 to 350, for example, limitingaccess to the mezzanine and upper side galleries, and reducingarchitectural lighting levels in upper areas, will allow the theater still toseem reasonably full. The main level of the Auditorium is entered fromthe rear on both sides through sound and light locks. From the entrypoint, audience members can either follow aisle access paths to thecross aisles (to access the lower seating area) or go up a few risers tothe rear of the upper stepped seating section. The mezzanine is alsoentered from the rear, and steps lead down to side galleries on bothsides. Open connecting stairs allow communication within theauditorium between the mezzanine and main levels at both sides nearthe proscenium wall, and the same stair system provides secure accessto the catwalk level.

The stage is organized in a conventional end-stage configuration inorder to allow it to easily accommodate as wide a range of performancedisciplines as possible in addition to video projection. A permanent 4’

BUILDING SYSTEMS

apron extension allows performers to work downstage of the proscenium

line and allows easy access from auditorium to stage. A crossover

corridor behind the upstage wall of the stagehouse (part of the

backstage circulation system described above) maximizes stagehouse

efficiency, permitting scenery and backdrops to play all the way to the

upstage wall.

The stagehouse is just under 50’ high to the roof, allowing maximum

high trim under rigging equipment of approximately 42’. The catwalk

system extends over the entire stage area (including three transverse

catwalks and wide connecting catwalk fly floors at both sides) and

over the auditorium (including two front-of-house catwalks and side

gallery positions). The control booth is at the rear of the main level for

ease of access, and house mix and designer’s table locations are

integrated with accessible cross aisle boxes.

Black Box / Studio Theater:

The Studio Theater is a flat-floor space with upper seating gallery on

three sides and a pipe grid overhead at approximately +20’ for

equipment mounting. A large loading door in the center of the fourth

wall allows easy movement of scenery and equipment from the

circulation corridor system. So the theater supports a variety of stage

configurations. Seating or stage platforms can be used to created

raised levels within the room. The Studio Theater seats approximately

125 to 150 depending on configuration, including seating at the gallery

level. The main level is entered from the public corridor in the music

area, and a sound and light lock allows circulation to the rear of the

room. The mezzanine level can be entered from the second floor, via

steps leading down to the seating gallery. However, an internal

connecting stair allows access between levels and can be used as

the primary entry point to the gallery if show configuration dictates.

The control booth is at the elevation of the second floor of the school,

so it overlooks the seating gallery.

Music Rehearsal Spaces:

Two main spaces are provided for large ensembles, one for band

rehearsal and one for chorus and orchestra use. The chorus/orchestra

room is large enough to permit separate simultaneous set-ups for

both uses, so that shared use does not involve moving chairs and

stands constantly. Both are double-height spaces with plenty of volume

for acoustical purposes. All large music rehearsal spaces are separated

by smaller, quieter uses for acoustical separation, and construction

details will also provide ample acoustical isolation.

In addition to the two large rehearsal spaces, a variety of small ensemble

and individual practice/lesson rooms are arranged in the music area.

Instrument storage and music library areas support both large rooms

and include instrument lockers for student use accessible from the

main music area corridor. A digital music lab supports teaching of

music appreciation, composition, arranging, keyboard technique, and

other electronic music functions. Storage for marching band equipment

is located with direct access to outside. The music spaces are easily

accessible from the main performing arts loading and receiving area

for movement of large instruments and equipment.

Accessibility

The entire performing arts complex is designed to meet ADA standards.In the main Theater, wheelchair-accessible boxes are provided alongthe entire main cross aisle and in proscenium boxes, and in themezzanine in boxes across the upper row. The lower orchestra sectionis sloped at 1:12 to allow wheelchair access to the front of the stagefor uses such as musicals (when “pit” orchestras may play in thatarea) or for events using live sign language interpreters for whichaccessible seating in front of the stage is required. The total numberof wheelchair spaces available will exceed the seven required for the

main Theater, and if events are offered for which the mezzanine isclosed, main level boxes will accommodate more than the minimumof five spaces needed based on the capacity of the main floor. Mostboxes allow for wheelchair “clusters,” where two wheelchairs are locatedside-by-side, each with a companion seat. The circulation systemthat leads from the auditorium to the stage (and off again on the otherside) allows access for everyone on the main floor directly to thestage, whether by wheelchair or ambulatory, with no need for wheelchairlifts. The control booth is also accessible by ramps.

In the Studio Theater, because total seating capacity is less than 300and the mezzanine gallery provides 25% or less of total capacity, themezzanine gallery is not required to be accessible. However, theschool may opt to install wheelchair lifts to make the gallerywheelchair-accessible if desired. The main floor seating configurationwill change for each production, but the main floor can easilyaccommodate the five wheelchair spaces required for the StudioTheater. The control booth, which is at the elevation of the secondfloor of the school, is fully wheelchair accessible.

Assisted listening systems will be furnished in both theaters, and allrehearsal and support spaces are fully accessible.

Pool shells of cast-in-place or pneumatically applied concretewill be provided depending on the results of the geotechnicalinvestigation, construction staging, cost, and site access. An optionto use either method may be included if appropriate for the soilconditions. Different swimming pool contractors use different methodsof concrete pool shell construction.

HYDROSTATIC RELIEF SYSTEMSA means of stabilizing the pool shell when abnormal subsurfacehydrostatic pressure occurs will be provided, which otherwise can

cause the pool shell to float when the swimming pool is empty. Thishazard is minimized if a full basement surrounds the pool tank; however,if the pool walls rest in an unexcavated mass, the danger does exist.

The design of a hydrostatic relief system is usually based upon thepredictable levels of the subsurface water table. Because otherdevelopments can also create a hazardous situation when the pool isempty, it is important to understand these various dangers and todesign a comprehensive system that will prevent destructive forcesfrom developing. Various systems have been developed includingautomatic check valves, concrete ballast, dehydration systems, refillingsystems and gravity drains. The primary issue, as in any preventativeaction task, is to understand the various kinds of hazards and damagethat may occur.

Even a benign water table is not justification to dismiss the potentialproblem. An unnatural hydrostatic pressure condition can develop if abreak occurs in a water pipe in either the fresh water system or thepool water system. This rapid introduction of water into the otherwise“dry” substrata can create an unstable condition for the pool shell. Inthe case of the fresh water line, the condition can go undetected formonths in certain circumstances. For this reason the pool will featuresome means of draining the substrata below the pool shell.

In addition to a conventional automatic hydrostatic reliefmechanism(s), it is recommended that a sight well be provided in thepool deck, adjacent to filter room or immediately outdoors of thenatatorium. Such a feature will allow the visual inspection of the watertable under the pool and in the case of the outdoor sight sump,dewatering can be conveniently executed.

POOL FINISHThe interior finish for the competition pool and the teaching/dive poolwill be Diamond Brite/Pebble Tec. Specialty tile will be provided forthe perimeter tile band, gutter nosing, wall targets, recessed steps,floor lane markings, depth markings, warning signs, and constructionjoint installation bands.

BUILDING SYSTEMS

DECK SIGNAGEDepth markings and warning signs for the pool(s) deck will be requiredby code in contrasting ceramic tile. Depth markings will be shown instandard and/or metric measurements. “NO DIVING” signs will beprovided at all pool areas with a depth of water 5’-0" or less. Depthmarkers will be provided per code at not more than 25 ft intervals.

OVERFLOW RECIRCULATION SYSTEMSIn modern swimming pools, the purpose of the perimeter overflowsystem is to receive and capture water at the pool surface. This wateris then transferred to the filter plant, either by direct suction connection,or through a surge tank, which helps stabilize the water displacementin the swimming pool.

A 12" deep rollout gutter will be installed on the competition pool anda deck level gutter will be installed on the teaching/dive pool. A surgetank will be required for all pools utilizing a gutter system.

FILTRATION SYSTEMSThe filters will be high rate pressure sand filters operating at a flowrate of up to 15 GPM per square foot of filter area. While manymanufacturers rate their system at 20 GPM/sq. ft., field experiencehas shown that the lower flow rate results in better water quality. Thesystem will be designed to completely turn over the competition poolwater every 5 hours and the teaching/dive pool water every 4 hours.

Filter room and filter face piping will be PVC Schedule 80 piping usedthroughout the pool(s) piping system (8 in. or smaller) because of itsnoncorrosive quality; however, only molded fittings are recommended.All flanges will be reinforced with a steel ring molded into the flange toavoid cracking due to vibration. Heat exchanger bypass piping will becopper or CPVC

Filter Alternate: Filtration will be a regenerative media filtration systemoperating at a flow rate of up to 1.6 GPM per square foot of filter area.The regenerative media filtration system will be supplied as a complete

operable system which may include face piping, control valves, filtercontroller, compressed air system for the filter, media filter pump, andall other required system components. The system will be designedto completely turn over the competition pool water every 5 hours andthe teaching/dive pool water every 4 hours.

PUMPING EQUIPMENTHorizontally mounted centrifugal pumps will be utilized for all the pool(s)recirculation pumps, and will be certified by the National SanitationFoundation (NSF) and bear the certification mark. Pump casing willbe cast iron fitted with a replaceable bronze case wear ring. Pumpimpeller will be enclosed type of cast bronze, statically and dynamicallybalanced, and trimmed for the specified design conditions. A hair andlint strainer will be provided, for each pump, constructed of fiberglassor epoxy coated stainless steel construction with a clear observationtop. Pressure gauges will be installed on the discharge of the pumpsand compound gauges will be provided at the intake port of the pumps,after the hair and lint strainer.

PIPING SYSTEMSExposed piping in the filter room and surge tank will be Schedule 80PVC for strength and resistance to corrosion. All piping below thefloor of the pool shell will be encased in sand and will be Schedule 80PVC.

All valves will be identified in the filter room. Valves will be describedas to their function and referenced in the operating instruction manualand wall mounted piping diagram to be prepared by the contractor.The pool(s) will utilize a combination of floor and wall inlets.

CHEMICAL TREATMENT SYSTEMSSodium Hypochlorite will provide the primary chemical sanitizing forthe pools and spa. The halogen requirement of the pools will beautomatically monitored and controlled by a chemical controller capableof monitoring parts per million of chemical and showing OxidationReduction Potential (ORP) in addition to the traditional readings ofsanitizer and pH.

CO2 will be provided as the pH Buffering System. The CO2 systemshall consist of CO2 storage tank(s), a lockable fill box for bulk delivery,a pressure reducing/regulating system, a feed and rate of flowadjustment control system, injection or mass transfer system, and allvalves, tubing, fittings and appurtenances required for a complete andoperable system.

An Ultraviolet Dechloramination and Disinfection System will be providedfor each pool so that the pool water will be monitored and treated byUV sterilization in the range of 220nm to 400nm to kill bacteria, viruses,molds and their spores and to continuously remove chloramines. Theconcentration of free chlorine residual will at all times meet therequirements of the Health Department authority having jurisdictionover the swimming pool. Any proposed UV system must have a ULlisting on the complete system and be listed under NSF Standard 50.

WATER CHEMISTRY CONTROLLERA programmable chemical automation system will be furnished for thepool(s) for continuous monitoring of water chemistry (ORP/HRR, PPM,pH and Temperature), Langelier Saturation Index, and for automaticcontrol of the chemical feeders, heater, and water level. Installation ofthe system will be as specified by the manufacturer. A factory-authorizedrepresentative will provide training to the owner and the training will bevideo taped per the specifications. Such a system will not only improvethe water quality of the pool, but will also improve the overall environmentof the natatorium because of the greater degree of chemical balanceof the water. This can result in much less aggressive atmosphericconditions.

INSERTS AND ANCHOR SOCKETSA. Anchors for grab rails and stair railings will be provided.B. Anchors for backstroke stanchions and water polo goals will beprovided.C. Heavy-duty cup anchors for all floating lane lines will be provided.D. Anchors for starting blocks will be provided.E. Anchors for diving boards will be provided.F.

FOOD SERVICE NARRATIVE

This is a six-line servery consisting of five “identical” service stationsplus one “quick service” or Grab n’ Go area for persons wishing reducedor augmenting service for lunches brought from home, for example.The servery is partitioned from the Main Kitchen and storages areasas opposed to an “open plan” relationship, and foods and beveragesare prepared, whether packaged or in bulk, hot or cold, and placed inroll-in, pass-through hot cabinets or refrigerators to maintain properserving temperatures. All service wares and utensils are pre-cycledor recyclable materials and are completely disposable. The intent ofthe design is to focus on the noon meal although breakfast service iscertainly available. The layout of the service lines and queues isintended to serve all participants in the first fifteen minutes of eachlunch period, leaving the balance of time for dining, chatting, andclearing.

EXECUTIVE SUMMARY HGHLIGHTS

• Five service lines, whether the one single or the two tandemgroups, have the same appliances and equipment, and eachhas its own cashier/validator.

• Each line is provided with a beverage cooler, self-servicerefrigerated display, flat deck service area, “pizza deck” hot area, fivefull-size hot (or ambient) food wells (with individual controls and drains),service overshelf/lighted shield with heat lamp, and a 16" “deliveryarea” at the end of each service line, in sequence.

• Patrons queue and land their selections on a tray slide at thecashier, complete the sale transaction, and drift into the seating area.A self-service ice cream novelty cabinet is mounted on each cashierstation.

• Menu offerings at each of the five lines may be identical or bedifferent at the discretion of the Director of Nutrition.

• Daily “Specials” may be served, or lines may be shut down if notneeded, due to large field event absenteeism, or foul weather days.

• The quick service line is provided with a beverage cooler, two self-

service refrigerators for cold foods and beverages, a triple soup/chili/stew station, small wrapped salads bar, an ice cream novelty cabinet,and the cashier/validator. Products are self-serve or packaged,therefore a handsink in the room is not a Health Code requirement.

• The Main Kitchen is provided with a large walk-in cooler and walk-in freezer that meet or exceed County standards. We recommendtime/temperature recording devices to monitor the status of the productinventories for HACCP Compliance.

• There are four “hot prep” and two “cold prep” worktable areasalthough they are interchangeable as needs present themselves.

• The cooking line is provided with six major appliances; three double,ten-pan convection ovens, one ten-pan steamer, a 40-gallon tiltingbraising pan (griddles, fries, stews, boils, poaches, and holds hotsauces at serving temp), and a six-open burner range with oven, forsmall amounts of ingredients or sauces for menu items.

• The Exhaust Canopy is a compensating hood with an automaticfire suppression system, and is 24’-0" long in two equal sections.

• The cook line is flanked by one each reach-in refrigerators andfreezer.

• All work stations are provided with hand washing sinks, single-use towels and soap.

• There is no formal “bakery” area.

• Vegeprep area (cold foods handled from raw ingredients) isseparated from hot food areas by a full-height wall; provided with alarge vegeprep sink with long drainboards, a large equipment and worktable, and both hot and cold areas have ready access to pans andservice pans for bulk set-ups.

• An automated scullery sink with power washer bowls is providedfor pan maintenance.

• There is no “dishwasher” area.

• Food waste disposers are provided in two areas, the scullery andthe vegeprep area.

• The Director of Nutrition’s office is situated to monitor kitchenand storage area access.

• The Dry Storage Room is large and will accommodate rollingracks of products delivered by Vendors.

• Staff toilet rooms, locker rooms, custodial sink, and “rag” washer/dryer are located away from the food handling areas. Recommend alockable power disconnect for the washer/dryer to avoid misuse andabuse.

• This is a Schematic Design plan, and is incomplete at this phaseand is missing corner guards, wall shelves, floor trench drains, utensilracks, work table drawers and sinks, rolling bins, and small tabletopmachines. These will be added.

EXPANDED NARRATIVE

Dissipating the Crowd

Students and staff approach the serving area from the central maincorridor and flood into the queuing spaces in front of the serving lines,choosing the line that is less stacked up or offers the selectionspreferred. We recommend the development of some means ofcommunicating the Specials of the Day, general daily menu, and servicelines available.

While not included in the project Scope of Work, this is an area wherethe development of a work-able identification system can greatlyenhance line flows and participation, pre-printed monthly menu sheetsposted about the campus bulletin boards have been a dated mainstayfor decades but can certainly be improved upon.

With the use of running LED menu displays in the entrance or in thedining room itself, (also great for announcements, birthdays, specialevents, athletic scores, and congratulations), “Tomorrow’s Menu”,websites, and other visual aids, the patrons are interested, engaged,and encouraged to participate in the food service. Cycled menus canbe composed and stored, rotating every twenty-one days on theaverage. Seasonal specials and holidays can be celebrated to livenup the service.



Served persons find their preferred seating group, unless assigned,and dine, socialize, and exit, depositing their used wares on the wayout, sorting recyclables, and condensing their refuse in concealedreceptacles around the dining room (not shown on the plan.)

Serving Stations

Five stations are replicated and one is for Quick-service. The QuickService “Grab n’ Go” station is first in sequence so that those patronswishing to get in and out quickly are the first served. Ahead of eachother standard service station is a foyer queuing area to absorb the“milling crowd”. There are no physical control crowd barriers.

Patrons enter the serving station and select a chilled beverage fromthe open-top cooler. Next, the patron encounters an open-faceairscreen refrigerator loaded with packaged cold entrees, salads,sandwiches, fruit, desserts, and beverages. The flat surface area cancontain baskets of treats, PC-pack condiments, utensils and napkins.

The hot food section offers a glimpse of the “pizza(s) of the day”,followed by the hot entrees (anything from burritos to three-item platelunches), served into/onto disposable wares brought up by the staffservers from behind the line. The “tray carts” are deposits of servicewares; no trays are made available to the patrons.

As the patron turns away from the hot service area, they queue andface the cashier area, and set down their selections on the tray slidethree positions ahead of the transaction. There is an opportunity tobuy an ice cream novelty if desired, or the patron can come back aftereating the hot/cold lunch, and buy an ice cream novelty, as the mainserving stream will have dwindled by that time in the lunch period.

Grab n’ Go Quick Service

It is not uncommon for 15-20% of students to favor this type of service.Perhaps they do not desire a large meal, or would rather spend theirtime socializing with their classmates. A variety of foods, beverages,and a few hot items can be offered but in principle nearly all items arepre-packaged, wrapped, containerized, or otherwise ready to “grab ‘ngo”. Hot soup, chili, or stews are ladled by the customer into one ortwo sizes of containers as in a grocery deli, and capped.

The open top/front beverage cooler is a typical forced air case holdingin this instance up to eight dairy crates of milks, punch, or juice incartons. The two airscreen cases are vertical with multiple levels oflighted shelving that support canned, bottled, or packaged beveragesof wide variety, or foods such as yogurts, fruit, pastries and cakes,salads, sandwiches, side orders (Cole slaw, potato or macaroni salads)and caffeine-based drinks.

Three hot soup wells are shown, each with a capacity of 11 quarts or28 12-Oz portions. The “tray line” is a two-level arrangement whereinthe lower level is used to set empty containers, lids, plastic flatware,condiments, napkins, and “stadium trays”, leaving the top level andcounters uncluttered for the display of selectable foods and beveragesonly. The soups are positioned under lighted counter-mounted shieldsper Health Department requirements.

A flat service area between the soups and salads can be used forpastries, muffins, cookies, brownies, or any other wrapped, ambienttemperature products or condiments. The cold pan (aka salad bar) isnearly 5’-0" long x 2’-0" wide and is covered by a lighted countershield. The pan is mechanically-refrigerated per NSF Standard No. 7,and does not require ice for cooling the products. The Director ofNutrition can devise a varietal menu of chef’s salads, meat salads,vegetarian offerings (tabuleh, couscous, hummus), fruits, green salads,and many desserts to fill the case. A two-section “Grab n’ Go Reserves”refrigerator is positioned in the corridor just outside the service area,for rapid replenishment of the displays during service dwells so thatfresh, filled displays are promoted.A reach-in ice cream novelties freezer is positioned just ahead of thecashier zone. This can be filled with ice cream cups, and the usualdrumstix, Eskimo pies, and other frozen desserts.All items are pre-priced and the cash register/validator is pre-programmed so that a rapid-fire transaction rate of sales can bemaintained. The five standard serving line register equipment is similarin selection, with under-counter cash drawer, POS touch screenregister, and card reader/validator touchpad, depending on the salesrecording and payment system selected by the school district.

Receiving and Storage

Starting at the receiving dock, which is shared with the otherdepartments of the school, the bay area should be dedicated to foodservices to reduce the commingling of food products and suppliescrossing delivery paths of non-food items, such as chemicals anddetergents, shop supplies (cleaners, paints and varnishes), gardeningchemicals, and general office and classroom supplies.

Most school food service deliveries are scheduled during strict windowsof time, are made using one or more large articulated trailer trucks,and combine refrigerated, frozen, and ambient loads. Many are bar-coded, palletized, and shrink-wrapped to speed handling and reducedock dwell time. Manual pallet jack, skid handlers should be procuredby the school to move palletized loads off of the trucks and off thedock apron to areas of breakdown and storage. We have indicated apair of 36" doors leading from the dock apron to the interior corridor ofthe Main Kitchen. This corridor is 7’-0" wide at the critical points anda grocery pallet is 40" x 46" leaving 44" clearance to walk past.

Other uses at any food service dock are holding of recyclables,dumpster access, and holding of Vendor’s returnable goods (racks,dairy cases, and hampers.) Space should be set aside out-of-sightas these are not attractive. A hot cold water dock hose bib is needed.

All goods are received on the covered dock apron, moved off to abreakdown area, and distributed (either by food service staff or in someinstances by Vendor personnel) to the Dry Storage Room, Walk-InRefrigerator, or Walk-In Freezer. Chemicals, disposable wares, andother non-food items are staged in specific dry goods area so to remainseparate from foods.

The Dry Storage Room is 300 SF and wide to allow parking of mobilecarts and racks within for security. Vendor’s racks would have to beoffloaded and reloaded. The Walk-In Cooler is 170 SF and the Walk-In Freezer is 200 SF, for a combined total of more than 400 SF. Theallocation between refrigerated and frozen storage may be changedwithout affecting the footprint.

BUILDING SYSTEMS

Employee Facilities

Separate garment changing and locker rooms for male and femalesemployees are indicated. Generally, school food service workers are80%+/- female, in which case, we have in some circumstancesrecommended separate small, unisex garment changing rooms, anda single, large non-enclosed locker area, where personal items andouter garments can be secured at random, thus conserving a largeamount of floor space and reducing the actual locker count. Restroomsremain totally separate from the changing and locker areas.

The layout and arrangement of the employee facilities will be executedby the architects. Also in the Employee facilities area are a custodialroom with service sink and small detergent rack, and a stacked linenwasher and dryer, intended for cleaning rags and mop heads, not forpersonal garments. General aprons, side towels, cleaning cloths,and perhaps head coverings, along with any special event linens, wouldbe contracted from a linen service company, with clean linens storedin the Dry Storage Room (or a special closet), and soiled linens inhampers secured on the loading dock. Such items possess value,and we suggest a lockable cage if not ventilated room, be provided tosecure vendor’s returnables.

Director of Nutrition Office

We have indicated a single office area of 94 SF, with windows facingcorridors. A single door between the kitchen and school corridor isindicated, for persons wishing to visit the office without crossing througha heavy food handling area. There are usually two or more work stationsin a food service office, and additional space may be required elsewhere.This needs to be determined by the school staff.

Main Kitchen

The kitchen layout in “circular” as to worker routes throughout. Cold,raw foods follow a clockwise flow into the vegeprep and cold foodsarea where the products are processed into ingredients for hot mealsor components for cold meals. Hot food ingredients or componentstravel directly into the hot food prep and then cooking zones, andwhen finished in “small batch lots” (for freshness) are placed in short-term, hot food holding cabinets with atmospheric and heat level controlsto maintain quality.

Soiled utensils, pans, trays, and serving pans from the serving linesare gathered from hot and cold working areas and transported on cartsto the Scullery area equipped with a turbo-wash sink system for speedand thorough cleansing, and clean wares are staged for re-use betweenthe cold and hot food production areas.

The Main Cookline faces the servery demising wall that is penetratedby roll-in, pass-through hot cabinets and refrigerators. Between thecooking line and holding units are a string of prep and panning tablesto convert bulk foods from large batch to small batch units for distributionamong the service lines.

Pizzas, as an example, will be pre-dressed and held chilled on bakery

racks, and progressively baked off, sliced and trayed in the kitchen

and distributed among the hot servery lines during the entire service

period, so that fresh and toasty pizza will be available from start to

finish. The same principles apply to other products such as burritos,

oven-fried potatoes and chicken fingers, and similar “fast-food” products.

There are no deep fat fryers in the kitchen cooking line.

Personnel and Service Flows

The serving line layouts are intended to accomplish numerous goals.

The layout allows ready movement of workers from station to station

behind the serving lines, rapid redistribution of prepared food inventories,

restocking of service items (trays, cartons and disposables), and

general oversight by supervisors.

The individual service lines promote separation of the patron lines

queues to reduce tension in the serveries, rapid choices by patrons of

not only what offerings to select but also which lines to join for speedier

service. Movement between the “behind the lines” area to in front of

the lines during service dwells for restocking, is promoted by three

distinct counter gaps that do not interfere directly with the queues of

patrons.

Dining Area Features

Seating layouts and table mixes are still in development. Provisions

for self-bussing of trash to depositories and separation of recyclable

goods will be provided. We do not have direction or a recommendation

for in-dining area condiment stations, napery or flatware, or microwave

ovens, because this is controversial and can be debated either way.

The advisability or not of such provisions depends largely on the

persuasion and temperament of those being served.
